nios2: fix r15 issue for gcc4

2010-05-28T14:56:03Z

The "-ffixed-r15" option doesn't work well for gcc4. Since we don't use gp for small data with option "-G0", we can use gp as global data pointer. This allows compiler to use r15. It is necessary for gcc4 to work properly. Signed-off-by: Thomas Chou Signed-off-by: Scott McNutt

Move architecture-specific includes to arch/$ARCH/include/asm

2010-04-13T07:13:12Z

This helps to clean up the include/ directory so that it only contains non-architecture-specific headers and also matches Linux's directory layout which many U-Boot developers are already familiar with. Signed-off-by: Peter Tyser
